Oh, I missed that.  My local hack assumes `.svg', but that is not enough
for the general use case.

Perhaps, we could save as `$BASENAME.out', detect the image format, and
then rename to `$BASENAME.svg', for example.  If the file is not an
image, we leave it as `.out'.

We can detect the image type with `image-type':

  (image-type "...-59b9176e65c9.svg") => svg

If the above is sufficient, the problem reduces to:

  how to compute the `$BASENAME'?

[`org-babel-tangle-comment-format-beg' does something similar.]
